What is a solar electric or photovoltaic system?

Solar electric systems, which are also called photovoltaic or PV systems, are reliable and pollution-free. They make use of a renewable source of energy - the sun. And PV systems for homes and businesses are becoming more affordable all the time.

A PV system can be a substantial investment. As with any investment, careful planning will help you make the right decisions for your home.

The basic building block of PV technology is the solar “cell.” Multiple PV cells are connected to form a PV “module,” the smallest PV component sold commercially. Modules range in power output from about 10 watts to 300 watts.

Ministry of New and Renewable Energy has laid out specifications for manufacture of solar power systems. These can be found here.
